HEATING SYSTEM.

Specification of Letters Patent.

Application filed January 20, 1908.

Patented Sept. 19,- 1911.

Serial No. 411,692.

T 0 all whom it may concern:

Be it known that I, BENJAMIN F. SEY- MOUR, a citizen of the UnitedStates of America, residing at Denver, in the county of Denver and Stateof Colorado, have invented certain new and useful Improvements inHeating Systems, of which the following is a specification.

This invention relates to improvements in heating systems for use indwellings, public buildings and the like and more particularly in thesystem shown and described in the application for patent, Serial 107363,filed by me in the United States Patent Office on the twenty-first dayof December, 1907.

The present invention has for its object to provide a receptacle withwhich the stand pipe and radiators, included in the system disclosed inthe above application, connect and which being subjected to thecalorific influence of a suitable heating appliance, serves as a boilerin which the circulating water is heated to the required temperature andinto which it is returned when cooled after having passed through therespective radiators.

A further object of my invention is to provide means whereby the fluidcontained in the boiler may be heated by the influence of a therewithassociated electrical heating apparatus.

I attain the above objects by the mecha nism illustrated in theaccompanying drawings in the various views of which like parts aresimilarly designated and in which Figure l represents a fragmentaryvertical section through the various elements comprised in my improvedsystem, Fig. 2 an enlarged transverse section taken along the line 22,Fig. 1, Fig. 3 an enlarged horizontal section taken along the line 33,Fig. 1, and Fig. 4c a fragmentary view of the lower portion of theapparatus illustrating a modified manner of construction.

Referring to the drawings, the reference numeral 5 designates a metallictubular conduit which extends vertically through the various floors ofthe building in which my system is installed and whose upper extremityterminates above the level of water contained in a tank 6. The lower endof the conduit 5 communicates with a central vertical bore 7 in acylindrical core 8 which is concentrically disposed within a cylindricalvessel 9 through which the water passes to and from the tank 6 and thetherewith associated radiators 10. The latter connect with the lowerportion of the tank 6 by means of the service pipes 11 and with theabove named vessel 9 by means of the return pipes 12. The receptacle 9is to this end formed at its upper portion with a compartment 13 intowhich the last named pipes project and which communicates with the bodyportion of the vessel by means of apertures 1 1 in the interposedhorizontal partition 15.

Within the compartment 13 is a check valve 16, composed of a disk whosecircumferential lugs 16 engage the cylindrical surface of thecompartment and which is spaced from the apertured partition 15 by meansof downwardly extending feet 16. When the pressure in the vessel 9exceeds that of the water in the return pipes 12, the valve 16 will belifted toward the latters exit orifices and thus regulates the supply ofcooled water to the main portion of the vessel, in ratio to the quantityof water heated and displaced by ascension through thestand pipe 5.

The partition 15 between the compartment 13 and the body portion of thereceptacle 9, in addition to providing a support for the valve 16,performs the function of retarding the: flow of cooled fluid into thelower part of the vessel for the purpose of mitigating the refrigeratinginfluence of the said fluid upon that which is being heated.

The preferably concave bottom of the lindrical receptacle 9 has acentral, threaded opening into which is secured a hollow screw plug 17,whose open, upper extremity projects into a chamber 18 which beingformed in the lower portion of the core 8', communicates with its axialbore 7. The chamber 18 is formed by a depression in the lower surface ofthe core and is separated from the interior of the surroundingreceptacle 9 by a bottom plate 19 provided with a plurality of radiallyextending openings 20, through which water contained in the vessel 9,may pass into the said chamber and into the therewith communicatinginterior of the plug. In connection with this feature I wish itunderstood that, if so desired, the plug may be made integral with theshell of the vessel 9, as shown in Fig. 4 of the drawings, or that thepocket produced there by may be formed in any suitable manner.

A disk valve 21, whose circumferential lugs 21 engage the cylindricalsurface of the valve chamber 18, normally rests upon the plate 19 andcloses the openings 20 until the pressure of the water in the receptacle9, supplied thereinto from the compartment 13, exceeds that of the fluidin the chamber 18 and the therewith communicating stand 31136. 1 Thelower portion of the hollow cylindrical plug or thimble 17 projectsbelow the bottom of the receptacle and it is this portion which while myapparatus in its operation, is principally subjected to the calorificinfluence of the subjacent heating medium.

Although I do not wish to limit myself to any specific form of heatingcontrivance to be employed in connection with my apparatus, I preferablymake use of an electrical appliance 22, which as is shown in Fig. 1 ofthe drawing, may be secured around the protruding portion of the plug 17and which consisting of a resistance coil of any suitable construction,may be connected by a thereto attached plug 23 with a socket of anyincandescent lamp circuit.

The receptacle 9 is surrounded by a mantle 24 which is intendedprincipally as a means to form an air acket around the vessel forpreventing radiation of heat and which may also be utilized as a supportfor the lower portion of my apparatus.

In the modified construction illustrated in Fig. 4, the referencecharacter 25 designates the pocket formed by the dependent appendage 26which in this case is integral with the vessel 9 and extends inwardlyinto the lower portion of the core 8.

Having thus described the mechanical construction of my improvedapparatus, the operation thereof is as follows :-The tank and otherelements comprised in my system liaving been supplied with water, thesmall quantity contained in the pocket formed by the hollow plug 17 isheated by the influence of the surrounding or subjacent calorific agentand rises, after it has attained a certain temperature, in the standpipe, to be discharged into the tank 6, while a like quantity of waterflows simultaneously from the valve chamber 18 into the interior of theplug. The heated fluid which thus collects in the tank, flows throughthe service pipes 11 into respective radiators 10, from where it isdischarged into the compartment 13 through the return pipes 12. Thecooled water passes subsequently through the apertures 14 in thepartition 15, into the space between the core 8 and the surroundingshell where it is subjected to the heat produced by the calorificappliance and from where it subsequently passes through openings in thebottom plate of the core to be raised to the desired temperature in thehollow plug. It will thus be observed that the water con tained in thevarious elements of my apparatus, is continuously circulated through theradiators included therein, entering them at a high temperature anddischarged therefrom when cooled, into the receptacle 9 where it isagain brought to the required temperature. 'The valves 16 and 21, whichrespectively control the flow of water through the exit orifices of thereturn pipes 12 and through the openings 20 in the bottom plate 19 ofthe core, promote by regulation of the supply of water to and from thereceptacle 9, the continuous circulation of water through the variouspipes and devices which together compose my heating system.

Having thus described my invention what I claim is 1. In a system of theclass described, an element comprising a vessel divided horizontally bya perforated partition, a core in the lower portion of the vessel spacedfrom its wall and having an internal cavity, means for establishingcommunication between the lower portion of the vessel and the internalcavity, an upright water conduit connected with the said. cavity, areceptacle connected with the conduit at its upper end, a radiator, andpipes connecting the latter with the receptacle and with the upperportion of the said element.

2. In a system of the class described, an element composed of a shelland a core spaced from each other, the said core having an interiorcavity in communication with the said space,a hollow plug depending fromthe said element in communication with the said cavity, an uprightconduit connected with the said cavity, a receptacle connected with thesaid conduit at its upper end, and a radiator connected with the saidreceptacle and with the said space.

3. In a system of the class described, an element composed of a shelland a core spaced from each other, the said core having an interiorcavity, and openings connecting the latter with the said space, a valveadapted to automatically control the flow of water through the saidopenings, a hollow plug depending from the said element in communicationwith the said cavity, an upright conduit connected with the said cavity,a receptacle connected with the said conduit at its upper end and aradiator communicating with the said receptacle and with the said space.

4. In a system of the class described, an element comprising a Vesseldivided horizontally by a perforated partition, a core in the lowerportion of the vessel spaced from its wall and having an internalcavity, means for establishing communication between the lower portionof the vessel and the said cavity, an upright water conduit connectedwith the said cavity, a receptacle connected with the conduit at itsupper end, a radiator, pipes connecting the latter with the receptacleand with the upper portion of the said element, a valve adapted tocontrol the communication between the interior of the lower portion ofthe said vessel and the cavity in the core, and a valve adapted to closethe orifice of the pipe which connects the radiator with the upperportion of the vessel.

In testimony whereof I have afiixed my signature in presence of twowitnesses.
